For sale is a collectible Magnum XL .46 model engine. 

The engine does come with a muffler. The engine does turn over nicely.  The fuel adjustment value works well and the throttle linkage.  There seems to be a modification done to the throttle linkage ( see photo ). The cooling vanes on the engine also  appear to be in good condition.  On the bottom of one of the hold down brackets is the number 4301.   The muffler also appears to be in good condition.   

Great engine for a collector of model engines.
